Abstract:

In this paper, Multi-Microgrids (MMG) are considered as future smart distribution grids, in which small scale energy resources (SSER) are main power generation units with small scales. Optimal operation of microgrids in defined intervals is carried out to achieve economic conditions in distribution systems. The defined operating problem is optimized using a heuristic algorithm considering uncertainties in loads and renewable energy resources (RERs). The probability density functions (PDFs) are used to encounter with the uncertainties. The total cost of the network is minimized by the algorithm. Then, each MG is evaluated from reliability point of view. Some new introduced reliability indices in the literature for MGs are used to evaluate the MGs' reliability. In proposed structure, the MGs are in interconnected mode and there is power exchanging between MGs. The particle swarm optimization (PSO) algorithm is applied to optimal power dispatch and the obtained results are compared by Monte Carlo simulation (MCS) method.

Reliability Assessment of Distribution Systems in Presence of Microgrids Considering Uncertainty in Generation and Load Demand

The microgrid concept provides attractive solutions for reliability enhancement of power distribution systems. Normally, microgrids contain renewable-energy-based Distributed Generation (DG) units, which their output power varies with different environmental conditions. In addition, load demand usually changes with factors such as hourly and seasonal customer activities. Hence, these issues hav...

Microgrids Reliability Evaluation with Renewable Distributed Generation and Storage Systems

This paper presents a model for reliability evaluation of Microgrids with Distributed Generation based on renewable energy resources. In this approach, DG participates in the network operation coordination as an active agent and not as a decentralized generation under which the utility has no control. Stochastic models are considered for representing generation availability related to wind ener...
